Dead Line (Liz Carlyle Series #4)

MI5 Officer Liz Carlyle returns in a powerfully suspenseful, psychologically riveting thriller to diffuse a terrorist plot.
 
As plans get under way for a Middle East peace conference at the Gleneagles resort in Scotland, MI5 Intelligence Officer Liz Carlyle is summoned to a meeting with her boss, who has just received an alarming tip: two individuals are mounting an operation to violently disrupt the conference and lay the blame on Syria, and Liz must stop them. No one knows who they are or exactly what they're planning, but given the stature of the conference attendees no chances can be taken. As the conference deadline draws closer, Liz keeps running into one dead end after another, and she begins to understand that the threat is far greater than she could have imagined.
